Feudalism is one of the standard memes of history, as per David Brin.[1] The essay is well worth reading, as well as the thesis that a new meme ("otherness") arose within Western Liberalism. In my mind Otherness is a saddle point, and worth investing in to protect.[2] [1] http://www.davidbrin.com/nonfiction/dogmaofotherness.html [2] https://en.wikipedia.org/wiki/Paradox_of_tolerance
Western Liberalism increasingly seems to just be a system by which you establish global feudalism. I guess it's good for a few generations. Hard to argue it's even good now though because even though we're wealthier than ever we're increasingly unhappy and mentally ill.
GDP per capita and even GDP per capita adjusted for PPP is also misleading because it uses the wrong basket of goods: focusing on things that dont matter.
People forget, wealth is not money. Wealth is the things you buy with money. Wealth is when you can afford the essentials of life: Shelter, food, water, medical insurance, education and transportation (with the costliest ones being Shelter and medical insurance). Consider the number of working hours the average person needs to expend to afford shelter and compare that to 500 years ago. I think you'll find that there hasn't been much improvement. In fact, in CA and bay area, I think you'll see that we're working even longer hours to afford basic shelter than 100s of years ago.
